" The want of a good monograph of this family has prevented 

 the writer from giving a complete list of the family. Occasional 

 specimens have been frequently met with, not referable in all 

 respects to the published descriptions, and are probably as yet 

 undescribed species, but as this is to a certain extent doubtful, 

 the writer did not feel justified in giving names to what might 

 be only varieties." [C. C. A.]
